Try: https://wiki.archlinux.org/index.php/USB_Storage_Devices#Poor_copy_performance_to_USB_pendrive Other possibility is a different kernel scheduler, more aware of disk load and desktop responsiveness, like linux-ckhttps://wiki.archlinux.org/index.php/linux-ck .

I have the kernel: Take a look at this article on LWN: https://lwn.net/Articles/572911/ In short: it may be fixed by changing /proc/sys/vm/dirty_background_ratio of even better /proc/sys/vm/dirty_background_bytes to some reasonable small value.

No matter copying to an external drive or internal HDD. I experience very terrible freeze. Last time when I was copying big files, I locked the screen on GNOME and went out. When I came back and found the copy was still in process since the LED of my HDD is flashing. I typed my password and waited nearly 3 minutes until it stopped freezing and unlocked my screen! This isn't a) the same as described above and b) not a kernelbug. It's simply the combination of (slow) hdd, usb and the scheduler. Processes like your gnome and other os-stuff are sleeping while higher-priority processes come in. But the biggest problem will be that your internal-drive + usb are blocking the bus and while writing and reading big files the access time for other processes can be very slow (your hdd is at max. usage rate). -- Best regards, StarBrilliant
